Abstract
Unilateral pulmonary vein atresia is a rare congenital anomaly. Its symptoms begin to manifest in childhood and a broad spectrum of clinical severity has been described, ranging from asymptomatic, recurrent pulmonary infection, severe hemoptysis, to death. Only a few adult cases with this condition, with no or mild symptoms, have been reported. Pulmonary angiography has been typically used for definite diagnosis. However, pulmonary angiography may be replaced with the current developing multidetector CT. This report presents an adult case with mild symptoms, diagnosed by multidetector CT.

Fig. 2
Rt. pulmonary vein atresia in 16-year-old man.
A. Axial CT scan (lung window) shows small right hemithorax with mild interlobular septal thickening in right lower lobe and right middle lobe.
B. Contrast-enhanced axial CT scan (mediastinal window) shows the small right pulmonary artery and normal left pulmonary artery.
C, D. Axial and coronal CT scan shows smooth margin of the left atrium with no pulmonary vein (thin arrows) and numerous dilated vessels seen on paraesophageal area, representing bronchial collaterals (thick arrow).
